This
automotive maintenance tutorial was specifically written to assist
owners of the third generation (2014, 2015, 2016, 2017, 2018 plus
maybe also the 2019 and 2020 model years) Toyota Highlander SUV
in changing a burnt out courtesy step light bulb located in the
housing at the bottom of the plastic interior door panel.

The new light bulb should have turn on
immediately as soon as you pushed in the power plug.

If not, press the "Unlock" button on the key
fob to re-activate the interior lights.

If you installed an LED bulb and it doesn't
work, try removing the bulb, rotating the electrical contacts 180 degrees
and pushing it back into place. Some LED bulbs are polarized and will only
work when the + positive and - negative contacts are in the correct
orientation.
